Yes it can, since the valves are one of parts that transfer heat from combution chamber. Other thing is that exhaust valve opened to long causes exhaust system to overheat.
If the valves are incorrectly adjusted it will hurt performance.
It can, because when the timing chain/ belt fails, the pistons and valve are no longer in time, and the valves can be pen when the piston comes back up. This can cause bent valves, and piston damage. this is wrong a 2.3 is not a critical clearance engine the valves will never hit the pistons.
It is possible if it was putting too much exhaust back into the engine causing it to run lean. I'd check for any computer codes for the EGR valve. They should tell you what is wrong.
Replacing the timing belt on an Interference engine, and doing it wrong, can cause serious problems. Busted piston, bent valve, cracked head, are a few.
If the transmission modulator valve is vacuum operated and it goes bad it can allow the engine to suck transmission fluid thru the engine causing the engine to blow blue smoke out the exhaust.
Generally, over time, the compression release will get out of adjustment. Remove the overhead valve cylinder cover (the dead cylinder for twin cylinder engine) and adjust the compression release with the cylinder at TDC. Loosen the adjuster locks and set intake valve clearance to between .004in. and .006in. Adjust exhaust valve clearance to between .008in. and .010in. Takes about 3 minutes to do this!
somtimes usually not
on some engine designs when the timing slips or is wrong the valve train will hit the pistons. something has to break, the valves, pistons, or the rods will bend.
engine has bad intake valve,
The wrong anti-freeze could cause the water to freeze in the engine. The wrong anti-freeze could cause abnormal corrosion in the radiator.
I'm not a mechanic / technician but I read once that the modulator valve for the automatic transmission has a vacuum line connected from the valve to the engine and that transmission fluid can be sucked into the engine if something goes wrong with the valve
They are adjusted with shims. Unless you have a supply of shims, this job is best left to a professional. this is wrong you can adjust the valve lash with a feel gauge intake is .018 to .022 the exhaust is .023 to .027 all in mm make sure the car is cold when you adjust the setting on the valve lash. the order to adjust the valve is when it is at rest
